CONCRETE PLAQUE AND METE [OD OF MAKING SAMIE.

Application filed October 24-, 1924. Serial No. 745,601.

concern:

Be it known that I, IRENE M. VASHING- won, a citizen of the United States of America, residing at Brooklyn, city of New York, county of Kings, State of .New York,

have invented certain new and useful Improvementsin Concrete Plaques and Methods of Making Same, of which the follow- My invention relates to the production of artistic plaques of cement mixtures which will present the effect of a painting on plaque, and on which is marked the outline canvas or other given fabric having a characteristic surface, and reproduce-any given design. The best method at present known to me, for practising my inventionis illustrated in the accompanying sheet of drawings in which:

Fig. -1 shows a sheet of canvas with a simple design of 'a' clover leaf appearing thereon.

Fig.2 is a plan view of said sheet with bodies of cement applied to certain portions thereof in the process of forming the plaque,

and

Fig. 3 is a cross section on line 3- 3 of Throughout the drawings like reference characters indicate like parts. 1 'is a sheet of canvas, burlap, or other material having a characteristic surface, a representation of which is to be reproduced-in the cement of the desired design, here shown as. a clover leaf 2. The sheet bearing the design is supported onaqy suitable plane surface 3, and a frame 4: o the desired size and shape is placed on the sheet 1. 6, 6, represent masses of hydraulic cement mixed with a green pigment laced on the sheet 1 over the sections of t e design which are colored green, and 7,a mass of such cement mixed with a yellow pigment which extends over those portions of the design colored yellow. A 8 represents 'a thicker backing formed of concrete containing a out three parts. of sharp sand intimately mixed with ydraulic-cement. 9 is a board on which the foregoing parts are assembled.

In operating according to my invention to make a cement plaque which shallrepr'oducetheappearance or effect of a painting of said clover leaf or other design on canvas I mix pigments correspondin to the colors to be reproduced with suita le masses of hydraulic cement, preferably neat, moisten referably the vmasses with the proper proportion of water to combine with said cement when setting, and place the colored masses so produced 011 the canvas over the portions ofthe design which are to have the same color in a layer of suflicient thickness to' form ance of a painting on canvas of the original design, being a replica of the canvas surface in the selectedcolors.

Preferably the original layer of colored before the concretebacking is added. This is done to make sure that none of the concrete displaces thelower layer of colored cement so as to appear on the face of the plaque. Preferably also pigments are used of mineral or other character which will not be soluble in the cement or affected by any of its constituents; This is to preserve sharpness of outline inthe design on the completed plaque. s

While I have mentioned the use of hydraulic cement, obviously other cements might be used if plaques of fireproof or other qualities characteristic of different varities'of cement are desired.

If it is desired to reproduce in the pla no the surface effect of any other materlal, such as "cartridge paper, for instance, the original design is-outlined on a sheet of that material and the cement applied thereto as above described. 7 p

The result is an indestructible cement plaque which may be used for wall or other decoration and will produce the effect of painting ,on canvas or anyfabric havinga characteristic texture or appearance.

Having describcdmy invention, I claim: l; The method of producing in a cement plaque a reproduction of a desi n resem bling a painting on any particu ar fabric which method comprises outlining the decement masses is allowed to partially set which a backing ofmoist concrete is added to the layer of colored cement and allowed to set thereon."

3. A method such as set out in claim 1 in which the cement is colored by mixing therewith, while dry, pigments which are insoluble in any of the constituents of said cement when wet.

4. As a new article of manufacture, a cement plaque having a surface colored to reproduce a particular design and reproducing the appearance of texture of a particular fabric. i

5. As a new article of manufacture, .a cement plaque reproducing the effect of a painting on canvas having a surface representing a replica of a sheet of canvas composed of areas of cement mixed with dif-v ferent colored pigments.

6. As a new article of manufacture, a plaque having a surface of hydraulic cement and a. backing of concrete, said surface presenting a replica of a;given fabric and containing mineral pigments mixed with the cement to reproduce a given design in colors,

whereby the effect of a painting of said design on said fabric is produced. 7

7. The method of producing in a cement plaque a reproduction of a design resembling a. painting on any particular fabric which method comprisesoutlining the design on a sheet of such fabric, applying masses of moist hydraulic cement colored to correspond to different portions of said design on the corresponding areas of said fabric in a layer of proper thickness, allowing the cement to set and finally stripping off said fabric from the face of the plaque so formed.

8. Themethod of'producing in a cement plaque a reproduction of a design. resembling a painting on any particular fabric which method comprises outlining the design on a sheet of such fabric, applying masses of moist hydraulic cement colored to correspond to different portions of said design on the corresponding areas of said fabric in a layer-of proper thickness, adding a backing layer of concrete containing hydraulic cement, allowing the cement-.to set and finally stripping off said fabric from the face of the plaque so formed.
